Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed June 18. 1907- Serial No. 379.646.

To all whom it may concern:

Be it known that I, CARL A. OARLSON, a citizen of the United States, residing at Barberton, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Composition-Applying Mechanism for Match-Machines, of which the following is a specification.

This invention relates to improvements in composition-applying mechanism for match making machines of that class, more espe cially, in which rows of splints are introduced to a traveling endless carrier and transported thereby through appropriate dipping and drying paths to a match-discharging station.

A machine of the class mentioned, embodying in its organization compositionapplying mechanism, is set out in Letters Patent of the United States No. 528,457,. dated October '30, 1894, to Beecher & Wright, which mechanism includes in its construction a composition-vat, within which are rotatably mounted a composition mixer and a composition-applying roller, together with differential driving devices therefor, whereby when the match machine is in actual operation, the said mixer and roller are rotated at a normal speed to effect,.respectively, the intimate mixing of the composition and the uniform application thereof to the ends of' the depending splints on the traveling match carrier, and whereby, when the machine is stopped, the said mixer and roller are rotated at a relatively slow speed to continue the stirring of the composition and thus prevent its settling and thickening within the vat and upon the roller, as will more fully appear by reference to said Letters Patent.

The object, primarily, of the present improvements is to simplify the construction and organization of the differential driving mechanism of the said patent, while retain-' ing the important and practical advantages thereof; and with this, and other objects in view, the improvements, stated generally, consist in providing the driving member for the mixer and roller with two loosely-mounted wheels, one of which is constantly driven at a relatively slow speed from a convenient source of power, and the other of which is driven at a normal speed from a moving tion, enlarged, through the pawl and ratchet devices, and adjuncts, for the mixer actuating shaft. Fig. 4 is a transverse vertical section, as on the line 44 of Fig. 3.

5 designates a suitable frame within which is supported a tank 6 having hollow Walls to afford a steam or hot water jacket, and 7 a composition vat resting upon the side walls of the tank and depending thereinto. The ends of the tank are open to permit the ready application or removal, endwise, of the vat to or from the tank, as occasion may require.

8 designates an open frame, constituting a mixer, which is mounted to rotate within the lower portion of the vat; and 9 a composition-applying roller which is mounted to rotate within and slightly above the upper portion of the vat. The shafts 1O, 11 of the mixer and roller, respectively, are journaled in suitable bearings in the end walls of the vat. These shafts are squared, or otherwise appropriately shaped, at one end of the vat, so as to couple readily with the correspondingly socketed hubs of intermeshing gear wheels 12, 13, respectively, when the vat is slid endwise into the tank. The shafts 14 15 of these wheels are mounted to rotate in. suitable bearings on the frame 5; the shaft 14 being prolonged and having a bearing for its outer end in a bracket 16 on the frame.

When the vat has been applied to the tank,'motion properly imparted to the shaft 14 is transmitted therefrom through the inteilmeshing gear wheels to the mixer and r0 er.

17 designates one of the transverse driven shafts carrying the actuating ear wheels 18 for the endless match carrier 19, a part only of which latter is indicated in the drawings.

The several parts above referred to are substantially similar in construction and virtue of the relative proportions of the gear ing, the bevel wheel 20 is continuously rotated at a relatively slow speed.

On the shaft 14 is keyed, or otherwise secured, a wide ratchet wheel 26. with the teeth of which engage two pawls 27, 28, which are pivotally mounted on the inner sides of two sprocketwheels,29,30,respectively. Springs, as 31, secured to the pivot pins of the pawls and to the sidesof the respective sprocket wheels hold the pawls normally in engagement with the ratchet teeth.

The sprocket wheel 29 is conveniently connected by means of a chain 32 with a sprocket Wheel 33 on the driven shaft, 17, for the carrier of the match machine, which latter wheel is positively driven from a suitable source of power in the usual manner. Hence, during the operation of the match machine, the sprocket wheel 29 is driven at a normal rate of speed and, through the action of the pawl 27 on the ratchet wheel 26., the shaft 14 is correspondingly rotated; the motion of said shaft being conveniently transmitted therefrom through the gear wheels 12, 13,

to the mixer and roller, respectively. During this operation, the bevel wheel 20 and its sprocket 30 are continuously rotated from the line shaft, but as. their speed is less than that of the sprocket wheel 29 the ratchet wheel turns in advance of, and is practically unaffected by, the pawl 28. When, however, the match machine is thrown out of o eration, the sprocket wheel 29 and its paw 27 are idle, and, in consequence, the pawl 28 on the slowly rotating sprocket wheel 30 accomplishes the rotation of the ratchet wheel and its shaft 14 with a corresponding movement of the mixer and roller so as to stir the composition and prevent it from settling and thickening within the vat and upon the roller.

It will be obvious that the power may be transmitted to the sprocket wheel 30 by means of a chain driven from any constantly moving source, in which case the bevel gear connections may be dispensed with; and, further, that the pawl 28 may be pivoted to the side of the bevel wheel, in which case the sprocket wheel 30 may be omitted. The; sprocket wheel 30 and the described bevel gear mechanism however, are employed, in order that such wheel may be connected through a suitable chain, as 34, with an overlying shaft. leadingto, and geared with, othercomposition-applying devices on the machine, when plural com osition devices are employed, as for examp e, in the production of so-called double-dipped matches.
